Sorry for the excessive "" in the title - I know I'm probably using the wro= ng terminology!
Son has a camera mount for his bike which is attached via a "bolt" which ti= ghtens up.
When it arrived, there was a plastic surround covering the hexagonal top of= the bolt so that it could be twisted and secured in place manually without= a tool.
However, he has subsequently bashed this on something and the plastic surro= und has snapped off, leaving just a bog standard "bolt" head, which fits in= to a 7mm socket. Any hints as to what I might need to search for to get so= me form of replacement head for this? =20
Cheers!
Matt
